HB 625, by Rep. Bill Mercer (R-Great Falls) , would eliminate the numeric nutrient standards under Montana’s water quality act. Nutrients are one of the leading causes of water quality impairment in Montana’s rivers, streams, and lakes. Because of the extensive impacts associated with nutrients, the U.S. Environmental Protection Agency (EPA) developed nutrient water quality criteria. Montana’s nutrient standards were adopted and approved in 2015 by the EPA. Montana is obligated to combat nutrient pollution through nutrient standards, and any attempt to repeal the standards is not in conformity with the U.S. Clean Water Act.
Passed the House Natural Resources Committee on a 9-6 vote. Passed the House Floor on a 60-39 vote. Heard in the Senate Natural Resources Committee on April 8th. Tabled in that hearing.
